	Bipyridine - Wikipedia, the free encyclopedia
		Bipyridine is one of the simplest polypyridine compounds.
		Bipyridine is a white solid, soluble in organic solvents, and slightly soluble in water.
		There are six isomers of bipyridine; among them, a well-known structure is 2,2'-bipyridine.

	Bipyridine Chemistry
		Despite their apparent simplicity, methyl bipyridines and other unsymmetrical bpys have long been difficult to make efficiently.
		A new and improved route to halomethyl functionalized bipyridine ligands was devised.
		Using (trimethylsilyl)methyl bipyridines as the starting point, an efficient synthesis of hydroxymethyl bipyridines was developed.

		The bipyridine bridge moiety is almost flat and the hydroxy groups are directed towards the zinc ion.
		In the first residue (left) one copper ion is symmetrically bond to the bipyridine nitrogens, an acetate oxygen and the hydroxylates of the ligand to form square pyramidal surroundings (Cu(1)…N(1) 1.954 Å; Cu(1)…N(2) 2.000 Å; Cu(1)…O(3) 2.342 Å; Cu(1)…O(1) 1.913 Å; Cu(1)…O(2) 1.913 Å).
		The bipyridine backbone is nearly flat, a torsion angle of -4.2° being observed.

		Academic Dissertation to be presented with the assent of the Faculty of Science, University of Oulu, for public discussion in Raahensali (Auditorium L 10), on May 28th, 1999, at 12 noon.
		Twenty-seven phosphine and six bipyridine ligands were synthesised and characterized.
		The phosphine ligands contain thiomethylphenyl, methoxyphenyl, dimethylaminophenyl, pyridyl, naphthyl and anthracenyl groups, and the bipyridine ligands thiomorpholine and piperidine groups.

	RuTrisBpy
		The filled subshell has spherical symmetry and any incoming ligands will face electrostatic repulsion from the electrons in the filled orbitals regardless of which direction they approach the complex from.
		Each bipyridine bonds twice to the metal center through the donation of the lone pair electrons on both nitrogen atoms.
		If one of the metal-nitrogen bonds is broken, the other metal-nitrogen bond will hold the ligand in place long enough for the broken bond to re-form.

		First-principles calculation of the conductance of a single 4,4 bipyridine molecule
		The conductance of a single 4,4 bipyridine (44BPD) molecule connected to two gold electrodes is calculated using a density functional theory based Green function method.
		The atomic geometry of such a molecular junction is constructed from the optimized structure of a gold trimer–44BPD–gold trimer complex.

		First, we develop efficient approaches to functionalized ligands and their metal complexes.
		Initially, our efforts concentrated on bipyridine systems; however, more recently, the polymeric metal complex design has also been expanded to include beta-diketonates and other ligand systems as well.
		Next, we test the compatibility of these reagents as initiators with various living polymerizations.
